- Wikipedia:NavFrame and Wikipedia:Collapsible tables - frankly speaking, I love 'em
- How to find the deletion discussion of an article:
- the awkward way: look in the Deletion log to obtain date and time of a deletion, then look at Wikipedia:Archived delete debates near that time to see which edit regards the unlisting of the page, then view the previous version.
- the probably not always working easier way: directly go to Wikipedia:Articles for deletion/ARTICLENAME
- Wikipedia:WikiProject Inline Templates

Equivalence Relation Example
editAn Equivalence Relation Partitions a set into Collectively Exhaustive and Mutually Exclusive subsets called Equivalence Classes.
- Original Set
- Partition
- Graph
- Directed Graph
- Equivalence Classes form "Squares" in Matrices.
- Matrix
Set Union can be used to test for Collectively Exhaustive (Union of all Equivalence Classes = Original Set) and Set Intersection for Mutually Exclusive (zero for any Intersection).
